TLDR
In this article, a 2D rectangular porous radiant burner is modeled as a spatially dependent heat generation zone, where the solid phase is assumed to be absorbing, emitting and scattering, while the gas phase is considered transparent to radiation.Abstract:
This paper deals with the heat transfer analysis of a 2-D rectangular porous radiant burner. Combustion in the porous medium is modelled as a spatially dependent heat generation zone. The gas and the solid phases are considered in non-local thermal equilibrium, and separate energy equations are used for the two phases. The solid phase is assumed to be absorbing, emitting and scattering, while the gas phase is considered transparent to radiation. The radiative part of the energy equation is solved using the collapsed dimension method. The alternating direction implicit scheme is used to solve the transient 2-D energy equations. Effects of various parameters on the performance of the burner are studied.read more
